Length of original M1R springs in SFC1000?

[redfox]

Hi all,

I've got a friend who discovered that one of his springs in his M1R forks, which is the longer of the two, had broken. So he wants a new set for example the one that can be seen on fleabay - Wirth progressive springs.

He measured the broken spring to be apprx. 480mm.
I'd like to know the original correct length (of both sides) and say service limit length and the length of the Wirth item(-s).
And eventual other things to be aware of with regards to change the springs in the Laverda version of the M1R.

Kind regards,
Jacques

I will have a look to see if I still have the set of springs from one of my SFC1000s. I can say when I tried changing the springs in mine it induced a speed weave. Unfortunately the engine chucked a rod before I had the chance to address the handling...

Mglp...
Also it would seem that one does have to modify the lower base of each spring to suit the internals in the forks, on some m.y.'s

Kind regards,

Got mine done at Maxton the bottoms are different to each other and they have to machine the right leg i think
